New Gen 3 650V IGBTA Soft And Efficient Switch For Industrial Applications
Recent development of trench stop IGBTs has led to very performant devices. They present lower static and dynamic losses, thus increasing the efficiency of the systems they are applied, even at switching frequencies above 20 kHz. However, high performance comes together with some challenges. Some of them are related to the intrinsic behavior of the device. For instance,small and non-linear parasitic capacitances result in non-controllable switching speed. In addition, parasitic inductances of the IGBT package, combined with those from the printed circuit board(PCB), can generate persistent oscillations in both collector-to-emitter and gate-to-emitter voltage.Such application issues make modern IGBTs difficult to be handled, and limit their use.
The new family of trench stop IGBTs from ROHM Semiconductor, named Gen 3, is intended to offer an optimal compromise between performance and ease of use. Due to its fast but smooth switching behavior, Gen 3 IGBTs are easy to operate even with small values of external gate resistor.Consequently, it is possible to obtain high system efficiency with minimum effort in the PCB design and electromagnetic interference (EMI) filtering.
This application note introduces the technical features of Gen 3 IGBTs, as well as their benefits in industrial applications. As examples, a portable welding machine and a DC/AC inverter are used to compare the performance of Gen 3 with other IGBT devices available on the market.
